The charge-density-wave (CDW) in elemental uranium is known to contain propagation vectors along all three principal crystallographic directions, that is, all of q(x), q(y) and q(z) are non-zero. Neglecting time reversal, this allows for four possible combinations, and thus possible q vectors. Theory has predicted that these are coupled in pairs so that the CDW state contains two different domains, each one being a 2-q state. Neutron-diffraction experiments with uniaxial stress have verified these predictions for the first time, and give further information relative to the weak incommensurate scattering arising from the boundary regions between the domains.
